Someone help me pleasw

Answer 1

`\bf \underline{Solution-} \\`

`\sf{ \sqrt[3]{ - 216} } \\`

`= \sf{ \sqrt[3]{ \bigg( (1)/(216) \bigg)} } \\`

`= \sf{ \sqrt[3]{ \bigg( (1)/(6) \bigg)^(3) } } \\`

`\sf{ = \bigg( (1)/(6) \bigg) ^{ \cancel3 * (1)/( \cancel3) } } \\`

`\sf = \bigg( (1)/(6) \bigg)^(1) \\`

`\sf = (1)/(6) \: \: \: \: Ans. \\`
